1. An image decoding method performed by a decoding apparatus, comprising:
obtaining image information including residual information through a bitstream;
generating reconstructed samples of a current picture, based on the residual information; and
generating modified reconstructed samples, based on an in-loop filtering process for the reconstructed samples,
wherein the image information includes a sequence parameter set (SPS) and picture header information referring to the SPS,
wherein the SPS includes a reference picture resampling enabled flag,
wherein the reference picture resampling enabled flag is related to whether reference picture resampling is enabled,
wherein whether additional virtual boundaries-related information is included in the SPS or the picture header information is determined based on the reference picture resampling enabled flag, and
wherein the additional virtual boundaries-related information includes information on a number of vertical virtual boundaries, information on positions of the vertical virtual boundaries, information on a number of horizontal virtual boundaries, and information on positions of the horizontal virtual boundaries.
